Evaluation of umbilical artery (UA) PI, middle cerebral artery (MCA) PI, cerebroplacental ratio (CPR) and umbilical-to-cerebral ratio (UCR) at > 37 weeks of gestation in singleton, morphologically normal pregnancies affected by GDM, was performed in order to estimate the association between ultrasound measurements at term and perinatal outcome. Regression linear analysis was used to estimate the association between fetal Doppler parameters and neonatal pH, neonatal Apgar score, neonatal weight and a composite adverse outcome.

Abstract

Objective The timing of delivery for women affected by gestational diabetes (GDM) is still controversial. Good clinical practice often suggests offering induction of labor at term in order to reduce the complications associated with this condition, while recent evidence supports expectant management. Fetal Doppler parameters represent a validated tool for testing fetal well-being at term and can select pregnancies that need increased surveillance. The aim of the present study was to evaluate the role of fetal Doppler parameters at term for the prediction of pregnancy outcomes in patients affected by GDM. Methods Prospective cohort study in a single center. Evaluation of umbilical artery (UA) PI, middle cerebral artery (MCA) PI, cerebroplacental ratio (CPR) and umbilical-to-cerebral ratio (UCR) at > 37 weeks of gestation in singleton, morphologically normal pregnancies affected by GDM, was performed in order to estimate the association between ultrasound measurements at term and perinatal outcome. Regression linear analysis was used to estimate the association between fetal Doppler parameters and neonatal pH, neonatal Apgar score, neonatal weight and a composite adverse outcome. The receiver operating characteristic (ROC) curve was used to estimate the possible predictive value of the above association. Results Our results on 130 women showed MCA PI to be the best predictor of perinatal outcomes in terms of low Apgar score at the 1st minute (p = 0.00), pH (p = 0.02) and composite adverse outcome (p = 0.05). UCR showed a significant correlation with neonatal pH (p = 0.02). No significant correlations for UA PI and CPR MoMs have been demonstrated in our population. However, the small sample size is a limitation of the study. Conclusion Evaluation of MCA Doppler and eventually UCR at term can be a useful tool to discriminate pregnancies affected by GDM that can benefit from IOL before 41 weeks in order to reduce complications related to this condition.
